Answer:
Step-by-step explanation:
9.1 h + 11.6 t = 9.98(60)
9.1 h + 11.6 t = 598.8 ........ <em>(1)</em>
h + t = 60 ........ <em>(2)</em>
h = 60 - t
9.1(60 - t) + 11.6 t = 598.8
546 - 9.1 t + 11.6 t = 598.8
2.5 t = 52.8
<em>t</em> = 52.8 ÷ 2.5 = <em>21.12</em><em> </em><em>≈</em><em> 21</em> (lb.)
<em>h</em> = 60 - 21.12 = <em>38.88 ≈</em><em> 39</em> (lb.)
Answer:
slope = - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = x - 2 ← is in slope- intercept form
with slope m =
Given a line with slope m then the slope of a line perpendicular to it is
= -
= -
= - 3
